Light Sources and LightTech offer high-quality standard germicidal 254 nm UV lamps in both ozone free and ozone generating solutions. The type of fused quartz used to make the body of the germicidal lamp determines the emission of the wavelength in UV 254 nm energy. Light is broken into colors and measured by wavelength in nanometers with UV light in the range of 254nm proven to eliminate bacteria, viruses and harmful contaminants. 254nm UV light is highly effective in sterilization and purification applications used to disinfect air, water and surfaces.

“L” or “Low ozone” generating lamps transmit up to 90% of their energy at the 254nm wavelength and typically utilize a doped fused quartz that blocks the emission of 185nm energy. “VH” or “Very high ozone” generating lamps are produced using clear fused quartz which allows for the transmission of energy at both 185nm and 254nm wavelengths.

The 185nm energy reacts with the oxygen in the air to produce ozone. In applications that require moderate amounts of ozone, we custom splice the two types of quartz together to form a custom “L” to “VH” ratio according to the customer’s specific requirements.

254 nm UV Lamp and 185nm Ozone Generating Lamp

254 nm UV Lamps

LightSources & LightTech’s low-pressure, mercury-arc germicidal 254 nm UV lamps are specially designed to produce the highest amounts of UV radiation – where 90% of the energy is typically generated at 254nm. This radiation is very close to the peak of the germicidal effectiveness curve of 265nm, the most lethal wavelength to microorganisms. UV 254 nm light is proven to destroy bacteria and viruses by altering the DNA of the cells harmful contaminants, even microorganisms naked to the human eye. (see graph).

Our 254nm germicidal lamps are used extensively in the air and water purification markets and have been utilized in applications such as food and beverage, medical, HVAC (Heating, Ventilation and Air Conditioning), pharmaceutical, the semiconductor sterilization industries and many others. Our germicidal lamps are essential components in many municipal drinking water facilities, waste water and ground water remediation industries.

185 nm Ozone Generating Lamps

“VH” (or Very High ozone producing lamps) generate energy at 185nm in addition to the 254nm wavelength.

The UV emission at 185nm produces abundant amounts of ozone in air. Ozone is an extremely active and effective oxidizer, destroying microorganisms as well as acting as a deodorizer.

A primary advantage of the ozone generated by our UV germicidal lamps is that it can be carried through the air into places not easily reachable by direct UV exposure.
